简单的春联效果展示

春联是中国传统节日春节期间的装饰，它代表了对新一年的美好祝愿和祈求。春联一般由两条横幅组成，分别称为上联和下联。上联和下联在内容上相互对应，形式上对仗工整，富有节日的喜庆气氛。在中国文化中，春联不仅是一种文学形式，也承载着人们对未来的希望和祝福。

下边我就用比较简单html、js、css做一个简单的春联效果。

function generateAndDisplayCouplet() {
    const coupletIndex = Math.floor(Math.random() * couplets.length);
    const couplet = couplets[coupletIndex];

    const upperCoupletElement = document.getElementById("upperCouplet");
    const lowerCoupletElement = document.getElementById("lowerCouplet");

    // 重置动画
    upperCoupletElement.style.animation = 'none';
    lowerCoupletElement.style.animation = 'none';
    upperCoupletElement.offsetHeight; /* 触发重绘 */
    lowerCoupletElement.offsetHeight; /* 触发重绘 */
    
    // 设置文本
    upperCoupletElement.textContent = couplet.upper;
    lowerCoupletElement.textContent = couplet.lower;

    // 应用动画
    upperCoupletElement.style.animation = 'unfold 2s ease forwards';
    lowerCoupletElement.style.animation = 'unfold 2s ease forwards 1s';
}

// 初始化页面时生成第一对春联
generateAndDisplayCouplet();
